2.4.2.60 additional information Thi4 is a suicidal enzyme undergoing only a single turnover Saccharomyces cerevisiae ? - ? 89 2.4.2.60 additional information mechanism starts with cleavage of the N-glycosyl bond of NAD followed by ring opening, tautomerization and loss of water. Reaction continues with imine formation, tautomerization, sulfide addition and cyclization. Elimination of two water molecules followed by a tautomerization completes the formation of the thiazole moiety Saccharomyces cerevisiae ? - ? 89 2.4.2.60 additional information mechanism starts with cleavage of the N-glycosyl bond of NAD followed by ring opening, tautomerization and loss of water.
